Super concentrate additive solution composition

A super concentrate additive solution comprising:

• a) water in an amount ranging from about 14% to about 38% by weight based on total weight of the super concentrate additive solution;
• b) a freezing point depressant in an amount ranging from about 12% to about 60% by weight based on total weight of the super concentrate additive solution;
• c) phosphoric acid in an amount ranging from about 1% to about 55% by weight based on total weight of the super concentrate additive solution;
• d) a water soluble polymer in an amount ranging from about 0.15% to about 20% by weight based on total weight of the super concentrate additive solution;
• e) a calcium compound comprising calcium ion in an amount ranging from about 0.1 mg/L to about 20,000 mg/L;
• and
• f) a magnesium compound comprising magnesium ion in an amount ranging from about 0.1 mg/L to about 15,000 mg/L;
• wherein a pH of the super concentrate additive solution is less than about 5.5;
• and
• wherein the super concentrate additive solution is substantially free of precipitate after storage at room temperature for at least one week.
